virtblk_result returns blk_status_t which is a bitwise restricted type, so we are not supposed to stuff it in a plain int temporary variable. All we do with it is pass it on to a function expecting blk_status_t so the generated code is ok, but we get warnings from sparse: drivers/block/virtio_blk.c:326:36: sparse: sparse: incorrect type in initializer (different base types) @@ expected int status @@ +got restricted blk_status_t @@ drivers/block/virtio_blk.c:334:33: sparse: sparse: incorrect type in argument 2 (different base types) @@ expected restricted +blk_status_t [usertype] error @@ got int status @@ Make sparse happy by using the correct type.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
